authorized"; rather, it means "not applicable".

Where do you get that idea? From an incorrectly printed Jepp chart
perhaps?

Check FAR 97.3, and I quote:

(n) "NA" means not authorized.

Please notice the quote I pasted from the TERPS manual. Also, please
read the notes on the pages I originally referenced. They state that
there is no applicable RVR (visibility) requirement for CAT IIIc. They
also state that CAT IIIc is operation with visibility unsuitable for
taxi.

How could an approach be authorized yet have the visibility requirements
part of it be not authorized? When you take that NACO plate into
consideration in light of the TERPS manual, not applicable is a
reasonable conclusion.
